Infoblox package from Exchange made by Marco Tizzoni nd Emanuele Scaicca,
Michiel van Pouderoijen: In latest firmware releases of Infoblox it can occur that there are service values returned in the SNMP values that are not in use and also have no description. Version 1.2 fails on these.

Monitors Cisco BGP Peers (CISCO-BGP4-MIB).
- creates one service for each peer/address family (IPv4 and IPv6)
- performance data include: peer uptime, prefixes accepted, advertised, denied, suppressed and withdrawn
v0.2: added support for more then one address family per peer

This check adds a test for misbalanced metadata chunks to the df check of a btrfs filesystem. Please refer to the github url for further information. Be aware that you have to patch the check_mk_agent in order to make this work!

Contains plugins and checks to monitor Docker Service, Containers and Images.
Prerequisite: pip install docker (Version 2.5.1 or newer)
1.2.1: The package is now compatible with CMK 1.4.0, too.
1.2.2: The plugin can now handle images without RepoTags (which were used as item name before)
1.2.3: Now compatible with CRE versions & more fault tolerant, esp. on heavily loaded machines
1.2.4: Bugfixes

Shows the size of a Mailbox Database and the count of mailboxes in there. The data is recieved from the plugin running on a Exchange 2010 mailbox database server. Corrected for Mailbox DBs with spaces in the name and Python Syntatic space "bug", including 64Bit Windows CMD "Sysnative" access.

Standard cmk Active Check check_dns uses nagios plugin check_dns in Version 2.2 which does not allow query types other than A.
Nagios Plugin Collection 2.2.1 has extended this with parameter -q
This check makes use of this.

In BIG-IP 11.2.0 and later, the F5-BIGIP-SYSTEM-MIB file contains the sysCmFailoverStatusId OID (1.3.6.1.4.1.3375.2.1.14.3.1) that can be queried through SNMP to determine the failover status of a BIG-IP system in a device group. see https://support.f5.com/kb/en-us/solutions/public/14000/300/sol14399.html

extension to Maximilian Thoma's "cisco_inv_cdp" plugin (http://www.lanbugs.de/howtos/monitoring-check_mk/inventory/check_mk-inventory-cisco-cdp-neighbors-extension/) which makes it hopefully more general for Linux Hosts too.

This check uses the lvsgsp binary to monitor the state of the LVS Loadbalancer VIP. It collect information of the actice and inactive connections from virtual LB Node to the real server. The params are changeable with WATO rule "LVS Connection levels".

This is an extension of the plugin found at http://git.mathias-kettner.de/git/?p=check_mk.git;a=tree;f=doc/treasures/memcached;hb=HEAD
It adds autodetection (copied from apache_status) and agent bakery integration.
Now reworked to support counters.

Sidebar Snapin to show acknowledged host/service problems by current user.
Also shows current host/service downtimes system-wide.
You can define what username format is used ("id", "alias", "firstname surname") in ~/local/share/check_mk/web/plugins/user_overview.py
v.1.1 - adjustments to work with cmk 1.4.0, maybe you have to remove the old snapin from the sidebar and add the new one manually. Old package for cmk < 1.4.0 can be found on github.
v.1.2 - fixed wrong view name, thanks to robert sander
v.1.3 - fixed two bugs (see github issues), thanks to robert sander
v.1.4 - now also works with nagios core

Special agent based on active check “check_bi_local”
the mkp contains an adjusted view "api_all_aggr" that enables the needed search context for getting more than one aggregation
v1.1: added acknowledgement tracking (like downtimes)

This plugin extends the zypper check shipped with check_mk. It lets you configure thresholds for updates (<=SLES11.4 recommended and security; >=SLES12.1 important and critical), the maximum duration security updates can be available until a warning or critical state is raised and the status a packagelock should raise.
